I introduced my female to my male the other week for an hour or so, all good, no aggression. I had to go away for a few days so today was my first chance to pair them up again.All looked ok but the male (who is slimmer but the same length as the proven female) after an hour started to bite the female (to which I instantly removed the female). While he wasn't biting and coiling I wasn't at all sure so thought to err on the side of caution and stop any escalation.
